Instructions for use 1

Introduction

Follow the operating and maintenance instructions provided in this manual to ensure years of

accurate and reliable service. Read these instructions thoroughly before using the instrument,

and then store these instructions in a safe place for future reference.

The Welch Allyn SureTemp Plus is a portable thermistor thermometer used for accurately

measuring body temperatures at oral, axillary, or rectal sites. The device measures temperature

by default in predictive (Normal) mode, during which it uses a predictive algorithm to calculate

patient temperature. If you cannot correctly measure the patient’s temperature in Normal

mode, the unit will automatically enter Monitor (Direct) mode.

Normal body temperature is a range, which varies from person to person and is influenced by

factors such as time of day and an individual’s level of activity, ingested medications, age, and

gender. A person’s normal temperature tends to decrease with age.

The following table shows that ranges of normal also vary by site. Do not directly compare

measurements from different sites.

This booklet provides informative tips and instructions for using the SureTemp Plus model 690

and model 692 thermometers. The chart on the following page provides details about the

differences between these SureTemp Plus instruments.

Warnings

WARNING No modification of this equipment allowed.

WARNING Patient injury risk. Prior to taking a temperature, instruct the patient not to

bite down on the probe as patient injury and damage to the probe may result.

WARNING Patient injury risk. Use only Welch Allyn single-use disposable probe covers.

A new probe cover needs to be used with each new temperature taken. Never take

a temperature measurement without a single-use probe cover securely attached. Failure

to use a probe cover can cause patient discomfort from a heated probe, patient cross-

contamination, and inaccurate temperature readings.

WARNING Patient injury risk. Inaccurate measurement risk. Oral/axillary probes (blue

ejection button at top of probe) and blue removable probe wells are used for taking oral

and axillary temperatures only. Rectal probes (red ejection button) and red removable

probe wells are used for taking rectal temperatures only. Use of the incorrect removable

probe well could result in patient cross-contamination. Use of the probe at the wrong

site will result in temperature errors.

WARNING Patient injury risk. When taking rectal temperatures, insert the probe tip

only 5/8 inch (approximately 1.5 cm) inside the rectum of adults and only 3/8 inch

(approximately 1 cm) inside the rectum of children to avoid the risk of bowel

perforation.

WARNING Inaccurate measurement risk. Never take an axillary temperature through

the patient’s clothing. Carefully place the probe in the axilla, avoiding contact with other

objects or material.

WARNING Patient injury risk. Continuous measurement durations of 3 minutes at the

oral and rectal sites and 5 minutes at the axillary site are recommended for accurate

measurement. Do not continuously measure beyond 10 minutes in any mode.

WARNING To ensure patient safety and temperature measurement accuracy, use only

accessories and supplies recommended or supplied by Welch Allyn.

WARNING Never use a damaged temperature probe. The thermometer consists of

high-quality precision parts and should be protected from severe impact or shock. Do

not use the thermometer if you notice any signs of damage to the probe or instrument.

If the thermometer probe is dropped or damaged, remove it from use and have it

inspected by qualified service personnel.

WARNING Inaccurate measurement risk. For rectal measurements, apply a thin layer of

lubricant to probe cover, if necessary, for patient comfort. Use of excessive lubricant may

affect reading accuracy.

WARNING Inaccurate measurement risk. To ensure optimal accuracy, always confirm

that the correct mode and site are selected.

WARNING Incorrect measurements can result in delayed or incorrect treatment. If you

suspect that the thermometer is delivering inaccurate measurements, first review the

instructions in the sections on temperature measurement in this manual for ways to

avoid inaccurate measurements. If you still believe that the thermometer is inaccurate,

contact a Hillrom Service Center for calibration.

1. Install the oral/axillary probe (blue ejection button) or optional rectal probe (red ejection

button) by inserting the latching probe connector on the end of the coiled cord into the

unit’s plug receptacle. Ensure that the connector snaps into place. The LCD will illuminate

for approximately 7 seconds and will then turn off.

2. Connect the appropriate removable probe well to the thermometer. Note that the cut-out

in the probe well fits over the probe cord strain relief. Ensure that the removable probe well

“snaps” into position and is completely seated to the thermometer. Place the probe into the

well.

3. Insert the box of Hillrom disposable probe covers into the probe cover storage holder. To

open the box of probe covers, remove and discard the tear-away corner. You will see the

ends of the probe covers in the box.

Mounting the unit

Mount the wall-mount bracket in a location such as an interior wall or wall divider so that the

thermometer remains at ambient room temperature. Mounting the unit on an uninsulated

exterior wall, in an area directly hit by sunlight, above heat radiators or powered equipment

(including computers and lights), or below air conditioning outlets is not recommended.

Proper mounting of the unit will prevent tangling of the probe cord with other equipment at

the patient’s bedside.

Oral temperature measurement

Using probe with blue ejection button and blue probe well

When used correctly, the SureTemp Plus thermometer accurately measures an oral temperature

in approximately 4–6 seconds. The ability of the SureTemp Plus thermometer to take an

accurate oral temperature requires correct user technique.

1. Mount the instrument so

that all other objects are

no closer than 4 inches

(10.25 cm) from the sides

and bottom of the unit.

2. Mount the wall mount a

maximum of 48 inches

(122 cm) from the floor.

3. Install the wall mount to

allow at least 12 inches

30.5 cm) clearance on top

of the instrument. This

provides ease of

removing and installing

the probe and probe well

or installing probe covers

onto the probe.

10 Welch Allyn® SureTemp® Plus

Taking an oral temperature

1. Ensure that the oral probe (blue ejection button) and the blue probe well are installed.

2. Holding the probe handle with your thumb and two fingers on the indentations of the

lips around the probe.

6. Hold the probe in place, keeping the tip of the probe in contact

with the oral tissue throughout the measurement process.

Rotating “walking” segments appear on the display, indicating

that measurement is in progress.

7. The unit will beep three times when the final temperature is

reached. The measurement site, temperature scale, and patient

temperature will display on the LCD. The final temperature will remain on the display for 30

seconds.

8. If you cannot correctly measure the patient’s temperature in Normal mode,

the unit will automatically enter Monitor mode. In this mode, measurement

time is extended. Either repeat the temperature measurement in Normal

mode in the opposite sublingual pocket or keep the probe in place for three

minutes in Monitor mode. The thermometer will not beep to indicate a final

temperature. Record the temperature before removing the probe from the site, as the

temperature reading is not maintained in memory.

9. After the temperature measurement is complete, remove the probe from the patient’s

mouth. Eject the probe cover by firmly pressing the ejection button on the top of the probe.

WARNING Do not take a patient’s temperature without using a Hillrom disposable

probe cover. Doing so can cause patient discomfort, patient cross contamination, and

erroneous temperature readings.

WARNING Verify that the probe cover does not come off prior to use. A probe cover that

comes off during use can cause asphyxiation. If a probe cover fails to stay on, then the

retention mechanism may be damaged. Remove the device from service for inspection

by qualified service personnel.

WARNING Use only Hillrom probe covers. The use of other manufacturer’s probe covers

or no probe cover may produce temperature measurement errors and/or inaccuracy.

WARNING Patient injury risk. Do not exceed the recommended temperature

measurement durations in Direct mode. Continuous measurement durations of 3 minutes

at the oral and rectal sites and 5 minutes at the axillary site are recommended for accurate

measurement. Do not continuously measure beyond 10 minutes in any mode.

temperature will remain on the display for 30 seconds.

5. If you cannot correctly measure the patient’s temperature in Normal mode,

the unit will automatically enter Monitor mode. In this mode, measurement

time is extended. Either repeat the temperature measurement in Normal

mode in the opposite axilla or keep the probe in place for five minutes in

Monitor mode. The thermometer will not beep to indicate a final temperature. Record the

temperature before removing the probe from the site, as the temperature reading is not

maintained in memory.

6. After the temperature measurement is complete, remove the probe from the patient’s

axilla. Eject the probe cover by firmly pressing the ejection button on the top of the probe.

7. Return the probe to the probe well. The LCD display will go blank.

Rectal temperature measurement

Using probe with red ejection button and red probe well

When used correctly, the SureTemp Plus thermometer accurately measures rectal temperature

in approximately 10–13 seconds.

Taking a rectal temperature

1. Ensure that the rectal probe (red ejection button) and the red probe well are installed.

The instrument will only operate in Rectal mode when the red rectal probe and probe well

are installed.

2. Holding the probe handle with your thumb and two fingers on the indentations of the

probe handle, withdraw the probe from the probe well.

3. Observe the flashing lower-body icon on the unit’s display. Load a probe cover by

inserting the probe into a probe cover and pressing the probe handle down firmly.

The probe handle will move slightly to engage the probe cover.

WARNING Long-term continuous monitoring beyond five minutes is not recommended

in the Axillary mode.

WARNING Probe contact with electrodes, bandages, etc., poor tissue contact, taking a

temperature over clothing, or prolonged exposure of axilla to ambient air can cause

inaccurate temperature readings.

WARNING Cross contamination or nosocomial infection risk. Thorough hand-washing

greatly reduces the risk of cross-contamination and nosocomial infection.

WARNING Do not take a patient’s temperature without using a Hillrom disposable

probe cover. Doing so can cause patient discomfort, patient cross contamination, and

erroneous temperature readings.

WARNING Use only Hillrom probe covers. The use of other manufacturer’s probe

covers or no probe cover may produce temperature measurement errors and/or

inaccuracy.

4. With the Rectal mode indicator flashing, separate the patient’s buttocks with one hand.

Using the other hand, gently insert the probe only 1.5 cm (5/8 in.) inside the rectum (less for

infants and children). The use of a lubricant is optional.

5. Tilt the probe so that the tip of the probe is in contact with tissue. Keep the hand separating

the buttocks in place, and hold the probe in place throughout the measurement process.

Rotating “walking” segments appear on the display, indicating that measurement is in

progress.

6. The unit will beep three times when the final temperature is reached. The measurement

site, temperature scale, and patient temperature will display on the LCD. The final

temperature will remain on the display for 30 seconds.

If you cannot correctly measure the patient’s temperature in Normal mode, the

unit will automatically enter Monitor mode. In this mode, measurement time is

extended. Either repeat the temperature measurement in Normal mode or keep

the probe in place for three minutes in Monitor mode. The thermometer will not

beep to indicate a final temperature. Record the temperature before removing

the probe from the site, as the temperature reading is not maintained in memory.

After the temperature measurement is complete, remove the probe from the patient’s

rectum. Eject the probe cover by firmly pressing the ejection button on the top of the probe.

9. Return the probe to the probe well. The LCD display will go blank.

10. Wash your hands.

Monitor mode temperature measurement

Using probe with blue ejection button (oral/axillary) or red

ejection button (rectal)

Monitor mode continuously displays the temperature of the probe for as long as the probe

remains in place at the measurement site and remains within the operating patient temperature

range. The patient’s oral and rectal temperature will reach final equilibrium in approximately

three minutes in the Monitor mode. Axillary temperature will reach equilibrium in

approximately five minutes in the Monitor mode.

Taking a temperature using Monitor mode

WARNING Patient injury risk. When taking rectal temperatures, insert the probe tip

only 5/8 inch (approximately 1.5 cm) inside the rectum of adults and only 3/8 inch

(approximately 1 cm) inside the rectum of children to avoid the risk of bowel

perforation.

WARNING Long-term continuous monitoring beyond three minutes is not

recommended in Rectal mode.

WARNING Washing hands greatly reduces the risk of cross-contamination and

nosocomial infection.

CAUTION Monitored temperatures are not stored in memory for recall.

WARNING Do not take a patient’s temperature without using a Welch Allyn disposable

probe cover. Doing so can cause patient discomfort, patient cross contamination, and

erroneous temperature readings.

Instrument security

The SureTemp model 692 thermometer is equipped with electronic security options designed

to reduce the risk of theft. These options include both Temperature count and Instant-on

security features.

Temperature count

The Temperature Count security feature allows you to take a set number of temperature

readings before the instrument goes into the security alarm state. The selectable counts are 25,

50, 100, and 200. As the instrument nears the final reading, it will display SECURITY COUNT as a

warning, along with a number representing the last 5 temperature counts (i.e., 5,4,3,2,1)

remaining on the security counter.

When the instrument enters the alarm state, it beeps for approximately 10 seconds. At this time,

the instrument displays SEC on the LCD along with SECURITY COUNT in the ID field in the

upper left-hand corner of the screen. The instrument is then disabled. Returning the instrument

to the wall holder resets the security count. If the count is set to “OFF” the temperature count

function is disabled and no security alarm will occur.

To set the Temperature count security feature, refer to the Service manual.

WARNING Use only Welch Allyn probe covers. The use of other manufacturer’s probe

covers or no probe cover may produce temperature measurement errors and/or inaccuracy.

WARNING The unit will automatically enter Monitor mode if the probe is withdrawn

from the probe well and is not replaced within 60 seconds of inactivity.
